Eddie,
Yes, most auto makers make a variety of commercial style vehicles like vans and trucks, but they tend to cater to the businesses overseas. You rarely see commercial Mercedes-Benz trucks and Vans because they don't sell many in the USA. They are usually very popular in the countries where they are made, but the US dealers don't stock or display them....I think nearly all the foreign made commercial vehicles are all special order items. Mercedes and Volvo have a few US dealerships and warranty/repair facilities for their big trucks, but it may only be a handful scattered across the country.
